I want to make Forward and Backward Slack Activity on Node Diagrams in MS Project 2010.
I display the Network Diagram view and choose Format > Box Styles. I Click the More Templates button and in the Data Templates, dialog, select an existing template and copy it. I Give the new template a name in the Data Definition dialog window. Towards the bottom of the Data Definition dialog window in the "Choose Cells" section I can specify which fields to place in which area.
I want to define four custom number fields ES, LS, EF, and LF.
ES = ProjectDateDiff([ProjectStart],[EarlyStart])/[MinutesPerDay]
EF = ProjectDateDiff([ProjectStart],[EarlyFinish])/[MinutesPerDay]
LS = ProjectDateDiff([LateStart],[ProjectFinish])/[MinutesPerDay]
LF = ProjectDateDiff([LateFinish],[ProjectFinish])/[MinutesPerDay]
but it seems MS Project doesn't allow formulas or custom fields.
How can I do a formula in a box field or formula ? Is it possible ?
